This is the Kingston MLPMR2/256GB bundle — a Canvas React Plus 256GB microSDXC card paired with Kingston's own MLPM microSD card reader and an SDXC adapter in one retail package, aimed at photographers and videographers who want both the fast card and a fast reader to actually realise its speed when offloading footage to a computer. The Canvas React Plus card is Kingston's high-performance line, rated UHS-II U3 V90 A1 with read/write speeds of 285MB/s and 165MB/s respectively — the UHS-II interface uses a 16-pin dual-channel design that's still backward compatible with older UHS-I devices and readers, just without reaching UHS-II speeds on them. The V90 rating guarantees a minimum 90MB/s sustained write speed, suitable for professional 8K and high-frame-rate 4K video capture. It's not compatible with SDHC-only devices or readers. Kingston covers the card itself with a lifetime warranty and the bundled MLPM reader with a 2-year warranty, sold together as one retail-packaged kit.
